This European Standard specifies qualitative and quantitative test methods of the visual assessment of defects of slurry surfacing. This European Standard is applicable to all slurry surfacing (roads, airfields and other areas). The visual assessment reports for both methods have identical records and thus both may be used to check the specification for visual assessment of defects. Defects emanating from the substrate (existing road) must not be taken into consideration. NOTE 1 The qualitative and quantitative tests may be used separately or sequentially. This may relate to different types of sites (for example lightly trafficked roads may not be required to be quantitatively assessed). NOTE 2 The test may be used to evaluate the durability of slurry surfacing.
